The source of the Waitara River lies in the very steep hill country to the east of Mount Taranaki/Egmont, near Tahora. After proceeding in a southwesterly direction toward Central Taranaki, the river abruptly turns to flow in a northwesterly direction to the Tasman Sea: meeting it at the coastal town of Waitara. The river once had a dock in Waitara, where export meat from the town's Thos. Borthwick & Sons freezing-works was loaded onto ships. However, this trade was subsequently conducted from New Plymouth's Port Taranaki until the works closed in 1995.
